To all whom t may concern: i

Be it known that l, lViLLiAM H. DAviDsoN,

-citizen of the United States, residing at vTheprimary object/or my invention is to f produceva burner of this type which.y will be of simple and `inexpensive constructioml'and eiicienjtin` operation.

Another object is to which: will afford ya Ybetter mixture ofthe volatilized oil'- and lairftof,insure ailcoinpiete combustionfof thefuelf v -v A further object of? theinventionis to provide an oi'lburner of-Qseparableglfparts y 't'aehmenthasv vap'a'ssag'ev 30 extending which are readilyV detachablev for cleaning.

The invention consists in 'tl'ienovel'conf struction, arrangementand conibination ofV be yhereinafter described and claimed.

. ln the accompanying drawings, f

Figure 1 is a view partly in plan and partly f in horizontal section of an oil burner embodying my invention. 30

Fig. 2 is a front elevational view of the same, one of the burner heads being shown invertical trans;

verse section. Y

Figs. 3 and4 are sectional views'through 3-3 and 4.-4 of Fig. 1. Fig is a detail' longitudinal sectional view to an enlarged scale of the gas discharge nozzle and retort tube.

In carrying out my invention I provide a manifold 10 having a cylindrical chamber 11 extending substantially its entire length and from the ends of which are upwardly extending tubular branches or hubs 12. Said hubs are formed with tapering upper extremities which lit into correspondingly shaped sockets provided in bosses 13 of circular burner heads, indicated generally by 14.

Each of said heads is composed of a base member 15 and a cap member 16 having intertting flange and roove connections 17 in their peripheral wa ls. K

The cap member 16 of a burner head is formed with an annular outer portion 18 of an arcuate shape in transverse section, as shown in Fig. 2, Aand affording a central cavity 181. Such annular portion 18 is slotted radially of the head to provide a plu- Y f Specc'aton of Letters Patent. i Application filedY pril 9, 1920.v Serial No. 372,469.

rality of kerfs 19throughwhich combustible gasy is emitted from the burner chamber 2O to be consumed in a series of flamesof stantially fish-tail shapes.

The heads are readily removed by lifting the same' from'the respective hubs12 and the members of eachl head are separably coupled as by means of screw bolts 21.

At or near its midlength the manifold 10v is provided at opposite sides with inlet and outlet openings 22 andV 23, respectively.

The ,opening 22 communicates with Ya chamber 2tformed^in the manifoldstructure and serves asa passageextending:longi tudinally Aof,thefmanifoldand is ,coiinected at one'jendof thelatter vto the leg l2zf fof a'A jsubstantiallyll-shaped pipe y26 whose other leg 27 isjit'apered andengages in the "sidecu't'j-v ylet 28 of aihollowfcylindrical attachmentf29.'V

nearly so, with the manifold 10 and is con- *y lnected by means of a T-litting 35A with a pipe l36 leading from an oil supply orreservoir, not shown'. 37 represents a rod extending axially through said retort and has a conical extremity 38 (Fig. 5) to constitute a needle valve, so called, with respect to an orifice 39 providedA in the outer end-of the coupling 33. y A

As shown in Fig. 5, the orice 39 has a plurality of branch ducts 4() leading into a cavity ltl'provided interiorly of the nozzle 32, the latter being provided with a single outlet 112 which is disposed to direct the generated `gas diametrically across the passage 30 and axially with respect to the pipe leg` 27. y

Subjacent to the retort is an auxiliary burner head 43 which is connected intermediate its length by a tubular bracket element 414 with the aforesaid manifold 10. The upper wall of the head 13 is formed with a central ridge 15 between two grooves 16, said ridge being provided with transverse slots 47. Suitable supporting means,

such as legs 48, are provided for the fold which, in turn, supports 4 the lYario-iis parts above referred toi" i To operate the device, the valve SSisirst,
